Myxoid liposarcoma is the second most common type of liposarcoma, normally located in deep tissues of the lower extremities and rarely in the mesenchyma of abdomen and pelvis We present a patient who, incidentally, showed a large pelvis mass. CT and MR revealed a loculated lesión with hypodense areas and very high signal in T2 respectively as well as heterogeneous contrast enhancement. The imaging findings of pelvic myxoid liposarcoma are nonspecific, but nevertheless a painless mesenchymal mass should be considered when we see lesions of myxoid aspect in the pelvic area without a clear relationship with defined anatomic structures.
黏液样脂肪肉瘤是第二常见的脂肪肉瘤类型，通常位于下肢深部组织，很少见于腹部和盆腔的间叶组织。我们报告一例偶然发现盆腔有巨大肿块的患者。CT和磁共振成像（MR）显示一个有分隔的病变，分别在T2加权像上有低密度区和极高信号，以及不均匀的对比增强。盆腔黏液样脂肪肉瘤的影像学表现不具有特异性，然而，当我们在盆腔区域看到黏液样外观的病变且与明确的解剖结构无明显关系时，应考虑无痛性间叶组织肿块。
